  In the face of the zero-carbon trend, Infineon actively deploys the third type of semiconductor   Huang Maoyuan said that Infineon, which has more than 50,000 employees worldwide, will focus on two major trends (Megatrend): decarbonization (Decarbonization) and digitalization (Digitalization), and four major areas: automotive (Automotive), industrial Industrial Power Control (IPC), Power Sensing (Power Sensing) and Sensor/Control System (Sensor/Control System) lead the world's technological trends and contribute to energy conservation and carbon reduction. From a technical perspective, semiconductors play a pivotal role in energy conservation and carbon reduction. Huang Maoyuan took "Innovative power semiconductors to create a low-carbon future" as the theme, explaining how wide-bandgap semiconductors (also known as the third type of semiconductors) become an important key to decarbonization at the technical level; at the same time, he also took Infineon as an example , detail Infineon's layout achievements in the field of wide bandgap semiconductors. Si technology will not disappear, but it needs to be supplemented by compound semiconductors   Huang Maoyuan mentioned that Infineon invested a lot of resources in the development of energy storage facilities. In addition to improving the efficiency of renewable energy such as photovoltaic power plants and other renewable energy injected into the grid; storing excess electric energy during peak ionization periods is more important. Yes, learn how to achieve the highest power density in a small footprint. Secondly, in terms of electric vehicles (EV), Infineon also provides a full set of technical assistance, such as OBC, Inverter, HV DCDC and energy management. After using Infineon's SiC technology, the driving distance of EVs can be increased by 5% to 10%. Huang Maoyuan believes that the most critical technical indicators for 5G are energy conversion efficiency and base station size, which are also highly related to power density. Huang Maoyuan said that in the development of semiconductor components, silicon material technology will not disappear, but some shortcomings still need to be supplemented by compound semiconductors. For example, SiC has advantages in high power and high switching frequency, while GaN has advantages in medium power and highest switching frequency. Advantage. Infineon will continue to increase investment in Si, GaN and SiC   Huang Maoyuan pointed out that Infineon has 12-inch silicon foundries in Dresden, Germany and Villach, Austria, respectively, and the 6-inch and 8-inch silicon production lines in Villach are also in This year it was converted into a SiC and GaN production line. In addition, Kullim in Malaysia will also invest more than 2 billion euros in the production of SiC and GaN power modules. The construction started in July this year and is expected to be completed in 2024. At the same time, a special assembly and testing plant for automobiles will also be built in Melaka, Malaysia. (Compiled by Du Changqing)
